The present invention relates to extractors, especially for treating warp beams.

This invention consists in the novelconstruction and combination of the parts hereinafter fully described and claimed, whereby a warp beam is centered and secured on the rotary shaft of a centrifugal extracting machine.

In the drawings,

Fig. 1 is a section through the improved extractor.

Fig. 2 illustrates in plan view the starshaped guide piece.

Fig. 3 is a section along line AB of Fig. 2.

Referring to the drawing, an annular support I) is mounted on the correspondingly extended vertical extractor-shaft a, which support carries the full warp beam 0. The conical part 6 of said support serves to center and reliably hold'the bottom end of the full beam on said shaft a. At approximately half height of the warp beam 0 a star-shaped guide piece (Z is mounted on the extractor shaft a, which star-shaped guide piece avoids the eventual flexure of said warp beam.

Onto the upper end of the warp beam 0 an annular sliding piece 6 with interior conical guide face is slipped over the vertical extrac tor shaft a and solidly fixed in position by means of the nut f.

The full beam is thus simultaneously well centered. on the extractor shaft and is prevented from sliding upwardly. The guide piece (Z has a hub which is secured on the shaft a, and has spaced vertical ribs adapted to engage with the warp beam, and which form vertical passages around the hub.

The adjustment to the centre of gravity is V automatically effected in the usual manner common to extractors with underneath drive.

I claim A centrifugal extractor for a warp beam,

comprising a rotary shaft, a conical support for the beam secured on the lower part of the shaft, means at the upper part of the shaft for clamping the beam against the said support, and a guide piece mounted on the shaft and having vertical ribs which project around it and are adapted to bear against the inside surface of the beam.

In testimony whereof I aflix my signature.
